Embodiment Construction

[0037] figure 1 A typical zipper or zipper generally indicated at 10 is shown. The zipper 10 comprises two side panels 12 having rows 13 of interconnecting elements (teeth) 14 . Also shown is the slider slider 15 and the upper stop 16 .

[0038]For the purposes of the present invention, the height of the interconnecting element 14 is defined as the dimension of the element in the inside-outside direction H of the zipper; when the zipper is ideally arranged as figure 1 The inward-outward direction H is perpendicular to the plane of the wing strip 12 as shown. The length L of the element 14 is defined in the transverse direction of the wing strip 12, and the width W of the element is defined in the longitudinal direction of the wing strip 12 ( Figure 1A ).

[0039] The interconnection element 14 is made respectively by joining together two half-elements obtained by means of stamping from advantageously flat sheet or plate material.

Abstract

Method for manufacturing interconnecting elements (14) for a slide fastener (10), comprising the steps of producing interconnecting half-elements (20) provided with a predetermined three-dimensional shape, by means of punching of said half-elements from a sheet, and forming said interconnecting elements (14) by joining together respective pairs of half-elements (20).

Description

technical field [0001] The present invention relates to the manufacture of interconnecting elements for zippers (zippers). The invention relates in particular to the manufacture of interconnecting elements having complex shapes for aesthetic purposes or for the individualization of zippers. Background technique [0002] Zippers as known basically consist of two side flaps carrying respective rows of interconnected elements, commonly referred to as tines or forks, and sliders for engaging and disengaging the aforementioned elements. The zipper may also include upper and lower stops for stopping the slider. [0003] Stamping is a widely used technique for manufacturing interconnection elements, especially if said interconnection elements are made of metallic materials. The state of the art in this field basically envisages that each element is stamped in a single piece from a flat metal sheet, also called sheet. Stamping is usually carried out in several stages; before stam...
